It was me who was knocking on the door this time and it was Sally who opened it. She welcomed me in to her smart suburban home and led me through to the living room where her daughter, Nicola, was waiting. Only a few days earlier they had both been kneeling at my feet, naked, with my cum dripping from their faces after the best blowjob I had ever had.
Even then, kneeling beside her naked mother, I saw something in her face that told me Nicola was not used to being the submissive one in any sort of relationship. I took her though to another room, leaving Sally on her knees, and asked her what was going on. She hesitated at first but then told me the full story.
"I've lusted after my mother ever since I knew what lust was," she admitted. "I've always wanted to see what lay beneath the respectable image of wife and mother that she has always shown to the world. I've suspected for a long time that there was more going on than she was ready to admit to but never knew how to raise the subject. Then when she told me what had happened with you I know this could my chance."
This was the last thing I had expected but we discussed exactly what she wanted to do with the older woman waiting for us in the next room and today was to be the culmination of that plan.
Nicola indicated that I should sit beside her on the couch while Sally was told to stand in front of us.
"Mother, I've always known you were secretly a slut in saint's clothing and the things you have been getting up to with Sandy prove this. Well, your sins have caught you out and now you will have to pay the price for your indiscretions. You no longer have just a Master but a Mistress too. I will be giving the orders today and Sandy will be recording everything we do. I'm not even going to ask you if you agree because I know you crave being ordered around. Today we will find out just how far you are prepared to go. Turn around."
I could see that Sally was tempted to disobey but one glare from her daughter was enough to change her mind and she did as she had been told. I was busy meanwhile making sure my camera was in working order, ready to record every single moment of what promised to be a wondrous day.
"Lift up your skirt."
Sally could feel herself getting quite warm between her thighs but, even more, she could feel her face burning with embarrassment as she prepared to expose herself to her daughter and her boss. She had already done so, and so much more, but here, in her own home, it somehow seemed worse, more wicked, more depraved, more deliciously sinful. She leaned forward to grasp the hem of her skirt and grasped the hem, pulling it up as instructed. It wasn't easy: although her skirt was of a respectable length as always, it was quite tight. She had to wiggle her bottom a bit as she pulled it up her legs, up over her smooth thighs, up until her bottom was revealed to her new Mistress and her Master.
It was such a beautiful sight. She was wearing stockings (as she had been instructed to do by Nicola) which were held up by a black lace garter belt with matching lace knickers. Everyone in the room knew her bum was one of her most enticing features and her lacy knickers presented her round cheeks in a very sensual manner.
"Bend over," was the next command from the couch.
It had been a long time since Sally had been asked to do this by her husband. He used to love the way she would flirtatiously lean forward, showing off her bottom, then smile back at him. But this was the first time she had done so in front of her daughter and the last thing she felt like doing was smiling. The pose seemed to accentuate her cheeks even more and she could feel her knickers pulling tight around them. The cheeks on her face were bright red.
"You know what to do, mother. Pull them down."
Taking a deep breath, she awkwardly threw her skirt up and over her back then reached behind herself to pull down her knickers. Even though she had known what was coming, she couldn't believe her daughter was making her perform like this. Because there was no other word for it; Nicola was forcing her mother to "perform" like a cheap slut and Sally knew that anyone who looked closely at the crotch of her knickers would know exactly how much she was secretly enjoying it.
She took hold of her knickers' waistband and slowly, slowly, slid them down. She didn't know why she was doing it like that but she hoped her audience of two were enjoying it.
I, of course, certainly was enjoying it, putting down the camera for a minute to enjoy the sight of Sally's backside being revealed. I knew how this must be making her feel but I suspected she would be enjoying it almost as much as I was, even if she would never admit it to herself. As her knickers came further down, I picked up the camera again, my cock beginning to stir as the crack between her cheeks was fully exposed.
"Stop there, mother."
Sally struggled to stay bent over but did as she was told. Her daughter's next instruction, however, made her face burn even brighter.
"Now pull your fat cheeks apart. Let's see what you're trying to hide."
Sally shuddered in embarrassment. She already felt sufficiently humiliated in this position but to have to do as Nicola instructed would be so shameful. No-one had ever looked at her there, not even her husband. He had never suggested it and she had never offered, preferring to think that one part of her body at least was private. Now her own daughter was telling her to show it off.
"Do you need to be reminded who's in charge here, mother?" asked Nicola in a threatening tone that Sally had never heard before.
Before the younger woman could get up from the couch, Sally reached back and spread her cheeks with her hands, at the same time her head lowering in total humiliation. She had never felt so ashamed but she knew that it wasn't just her burning cheeks that were being affected; her pussy was leaking so much that it must have been obvious to her boss and her daughter.
"Very nice, mother. You may stand up now."
Sally was relieved to let go of her cheeks and straighten up. She did, however, wonder what her daughter was going to demand of her next – and she had every right to be worried. She began to pull her knickers up when Nicola stopped her.
"Leave them where they are, mother, and come over here."
Sally let her skirt fall back down and waddled more than walked towards us, trying not to let her knickers fall down around her ankles. Taking little steps, but with her legs wide open to stop her underwear falling down, she eventually stood deferentially in front of us.
"Take a seat, mother."
I got up and Sally smiled in gratitude as if I was offering her my place like a gentleman should. In truth, I knew what was coming next and I wanted the two women to have as much room as possible. I also wanted to be in the best position to record Nicola playing with her mother.
